, SPRING-WHEEL.

Specification of Letters Patent. v

Application filed October 11, 1913. Serial N 0. 794,703.

To all wle am it may concern 7,

Be it known that 1,;VV1LL1AM H.IA BBO'IT, citizen of the United States, resldlng at Gwinn, in the county of Marquette and State,

of Michigan, have invented certain new and useful Improvements in Spring-Wheels, of which the following is a specification, reference being had to the accompanying drawings. i i V This invention relates to improvements in spring wheels and has for its principal object to provide a highly efficient andserviceable wheel particularly designed for use upon motor vehicles whereby the ordinary pneumatic tire may be dispensed with.

The invention has for another and more specific object ,the provision of a wheel embodying a plurality of radially disposed casings open upon .one side, pins mounted upon the wheel hub extending into the inner ends of said casings, springs arranged upon said pins and disposed within the casings, and a removable cover plate for the open side of said casings.

My invention has for another object to provide a spring casing of improved construction, a removable cover plate for one side of said casing, and means for removably locking said cover plate in position.

My invention has for still another object to generally improve and simplify the construction of spring wheels,.and to produce a device which is extremely durable in actual use and may be manufactured at compara' tivelysmall ccst. I

With the above and other'objects in View as will become apparent as the description proceeds, the invention consists in certain construction, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the inven tion, reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a partial side elevation of a spring wheel embodying my inyention in its preferred form, a portionof the cover plate for the spring casings being broken away; Fig. 2 is a section taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4C is a detail perspective view of one of the casing plates; Fig. 5 is an enlarged perspective view of the locking device for the cover plate of the casing.

Referring in detail to the drawings, 5 designates the wheel hub which. is mounted upon the axle spindleof the vehicle in any approved manner.

Thewheel proper includes an inner rim 6 and an outer rim 7 which are connected by means of a plurality of radially disposed spokes 8. p p V 9 indicates an annulus in which a plurality of radially extending pins 10 are secured in any preferred manner. These pins extend into the inner ends of the radialcasings 11 the outer ends of which are secured in the inner rim jmember 6. Each of the casings 11 includes a body plate 12. If desired, the

body plates 12 of the series of casings may be formed from one piece of metal, or the same can'be secured together-at their inner 13 designates the side'plates of each 'casing which are secured'to opposite edges of the body plate 12by suitable rivets 14. To

- the other or outer edges of the side plates 18, adjacenttheir innerends, pins 15 are fixed.

Contiguousto the outer end of each of the 18 normally act to maintain the wheel proper in concentric relation to the hub 5.

An outer face plate 19 for the series of spring casings 11 is formed from a single sheet of metal and includes a central cylindrical portion 20 which accommodates the outer end of the hub 5 and the radially disposed arms 21 which conform in shape to the shape of the casings 11. These arms are provided in their edges with openings 22 and 23 respectively, to accommodate the pins 15 and 16 upon the side plates of the spring casings. Upon the outer end of each arm 21 of the cover plate, a locking device is mounted. This locking device includes a lever 2a which is pivoted intermediate of its ends as at 25 upon the arm 21. Upon opposite sides of the pivot 25, the oppositely extending locking plates 26 are pivotally attached. The outer end of each of Patented. Ju1y21, 1914..

side plates, an additional pin 16 is secured,- said latterpins being slightly longer than {the inner pins;15 and provided with notches j17. The particularpurpose of these pins which are mounted upon the sideplates will :be later referred to. I

these plates is provided in its upper edge.

plates. One end of thelever 24: is provided with a lug 28 which is adapted to be engaged by a spring catch plate'29m'ounted' upon one of the locking plates 26. From this construct-ion, it will be apparent that when the cover plate is arranged in position over the spring casings 11, it is simply necessary to force the levers 2-1 downwardly to move the locking plates 26 inwardly toward each other into locking engagement with the pins-16. The other pins 15 on the side plates or the casings extend through the inner openings 22 in the arms of the cover plate and are flush with the outer face of said plate.

Upon the outer rim 7 of the wheel, a solid rubber or metal tire 30 is secured.

From the above description, it is believed wheel proper for movement with relation to the hub 5 so that all shocks or jars will be absorbed by said springs and not transmitted to the body ofthe vehicle. improved wheel structure is also extremely durable and serviceable in actual use. The cover plate 19 may be veryeasily and quickly removed should any one of the springs 18 be broken, and said spring replaced by a new one. The locking devices on the arms of thecover plate will securely retain said plate in position.

It will furtherbe understood that my invention is susceptible of a great many modifications in the form, proportion and ar- .rangement of the several elements and I therefore reserve the right to resort to all such legitimate changes as may be fairly :embo'cn'ed within the spirit and scope of the invention, as claimed.

Having thus described the invent-ion, Whatis claimed is:

1. The combination with a spring wheel including a plurality of cushioning springs, of a casing for each of said springs, said casings being open upon one side, pins secured to the side walls of each casing, a cover plate embodying a-plurality of arms adapted for engagement upon the open sides of the respective casings and provided with openings to receive said pins, and a pair of locking members movably mounted upon each of said arms for engagement with said pinsto removably lock the cover plate to the spring casings.

2. The combination with a spring wheel including a plurality'of-cushioning springs, 0d a casing for each of said springs open upon one side, pins projecting from each of the-side walls of the casing at its open side, a cover plate embodying a pluralityof arms, said arms oeing' adapted for engagement over the open sides of the respective spring casings, and provided with openings to receive the pins thereon, and locking devices mounted upon the outer ends of said arms,

each including a pair of movable locking elements and a lever toactuate-the same, said elements being adapted to engage the pins upon the casing walls and removably lock the cover plate in position thereon.

In testimony whereof I hereunto afiix mv signature in .the presence of two witnesses. VVILLIANI H. ABBOTT. Witnesses:
